中文摘要：

以1-金刚烷甲酸为原料,经酰化,取代和还原反应制得N,N-二甲基-1-金刚烷基甲胺（1）;1与双子季铵盐（2）在无水乙醇中反应合成了一种新型的金刚烷基杂双子表面活性剂——1-（N,N-二甲基-1-金刚烷甲基溴化铵）-6-（N,N-二甲基-十二烷基溴化铵）-己烷（3）,总收率30.9%,其结构经1H NMR和元素分析表征。采用表面张力法研究了3的表面活性。结果表明：3具有较强的聚集能力和界面吸附能力,其cmc,γcmc,p C20,Γmax,Amin分别为1.18 mmol·L^-1,35.5 m N·m^-1,0.48,2.63μmol·m^-2和0.63 nm^2。

英文摘要：

N, N-dimethyl-1-adamantane-methanamine （ 1 ） was obtained by acylation, substitution and reduction from 1-adamantane carboxylic acid. A novel heterogemini surfactant, 1-（,N,N-dimethyl-1- adamantanemethyl-ammonium bromide ） -6- （ N, N-dimethyl-dodecyl ammonium bromide ） -hexane （ 3 ） was synthesized by the reaction of 1 with gemini quaternary ammonium salt （2） in absolute ethyl alco- hol with overall yield of 30.9%. The structure was characterized by ^1 H NMR and elemental analysis. The surface activities of 3 were investigated by surface tension method. The results showed that 3 exhibited strong aggregation and adsorption ability with cmc = 1.18 mmol · L^-1 ,γcmc = 35.5 mN · m^-1 , pC20 =0-48, Гmax =2.63 μmol·m^-2 , Amin =0.63 nm^2.
